ST. LOUIS, JUNE 8, 2006 - Spartech Corporation (NYSE:SEH) announced today its
operating results for its second quarter ended April 29, 2006.

SECOND QUARTER 2006 HIGHLIGHTS:

     EARNINGS FOR THE QUARTER WERE $28.0 MILLION COMPARED TO $6.3 MILLION FOR
     THE PRIOR YEAR QUARTER AND RESULTED IN NET EARNINGS OF $13.9 MILLION WHICH
     WAS THE HIGHEST NET EARNINGS QUARTER IN COMPANY HISTORY. OPERATING EARNINGS
     BEFORE STOCK OPTION EXPENSE AND SPECIAL ITEMS WERE $29.2 MILLION COMPARED
     TO $24.3 MILLION FOR THE SECOND QUARTER OF 2005. NET EARNINGS EXCLUDING
     THESE ITEMS WERE $14.7 MILLION.

- -    NET EARNINGS WERE $0.42 PER DILUTED SHARE, AFTER STOCK OPTION EXPENSES AND
     SPECIAL ITEMS, COMPARED TO $0.00 PER DILUTED SHARE IN THE SECOND QUARTER OF
     2005. EARNINGS PER DILUTED SHARE BEFORE STOCK OPTION EXPENSES AND SPECIAL
     ITEMS WERE $0.44 COMPARED TO $0.35 IN THE SECOND QUARTER OF 2005. EARNINGS
     FOR THE FIRST HALF OF 2006 WERE $0.65 PER DILUTED SHARE EXCLUDING THESE
     ITEMS COMPARED TO $0.43 FOR THE SAME PERIOD LAST YEAR.

- -    CASH FLOWS PROVIDED BY OPERATIONS INCREASED TO $26.1 MILLION FOR THE SECOND
     QUARTER OF 2006 COMPARED TO $22.0 MILLION FOR LAST YEAR'S SECOND QUARTER.
     THIS ENABLED THE COMPANY TO PAY DOWN $25.2 MILLION OF DEBT, AND AT THE END
     OF THE SECOND QUARTER THE COMPANY HAD NO DEBT OUTSTANDING ON ITS EXISTING
     BANK CREDIT FACILITY.

SUBSEQUENT EVENTS AND OUTLOOK:

- -    THE POSITIVE CASH FLOW FROM OPERATIONS OVER THE PAST FOUR QUARTERS HAS
     PROVIDED THE OPPORTUNITY TO PAY DOWN MORE THAN $110 MILLION IN DEBT AND
     RESULTED IN OUR LOWEST DEBT TO EQUITY RATIO IN THE LAST TEN YEARS. THE
     COMPANY HAS UNDERTAKEN A SERIES OF CAPITAL STRUCTURE TRANSACTIONS
     SUBSEQUENT TO THE END OF THE SECOND QUARTER THAT WILL REDEEM $150 MILLION
     OF HIGH INTEREST RATE CONVERTIBLE PREFERRED SECURITIES WITH $50 MILLION OF
     5.78% FIXED RATE DEBT AND $100 MILLION OF BORROWINGS FROM OUR BANK CREDIT
     FACILITY OR CASH ON HAND. THE AVAILABILITY UNDER THIS FACILITY HAS BEEN
     INCREASED FROM $200 TO $300 MILLION WHICH MAINTAINS OUR FLEXIBILITY TO
     QUICKLY FINANCE ACQUISITION OPPORTUNITIES.

- -    AS A RESULT OF SIGNIFICANT PROGRESS TO DATE IN OUR BUSINESS IMPROVEMENT AND
     BALANCE SHEET MANAGEMENT EFFORTS, THE COMPANY IS INCREASING ITS EARNINGS
     GUIDANCE FOR FISCAL 2006 BY $0.05 PER SHARE TO A RANGE OF $1.28 TO $1.38
     EXCLUDING THE EFFECTS OF FAS 123(R) AND SPECIAL ITEMS. THIS RESULTS IN
     GUIDANCE OF $1.22 TO $1.32 PER SHARE INCLUDING THE IMPACT OF STOCK OPTION
     EXPENSING OF APPROXIMATELY $0.06 PER SHARE FOR THE FULL YEAR, BUT BEFORE
     THE IMPACT OF SPECIAL ITEMS RELATED TO RESTRUCTURING AND DEBT REFINANCING
     ACTIVITIES.

OVERVIEW OF RESULTS

Net sales for the second quarter were $389.3 million compared to $377.7 million
in the second quarter of 2005, representing an increase of 3%. This total was
the result of a 4% increase in price/mix over 2005, with underlying volume in
our Custom Sheet & Rollstock segment down 2% while our Color & Specialty
Compounds segment volume was up 1% over the prior year's second quarter. The
price/mix increase reflects selling price changes from the management of raw
material and conversion cost fluctuations, and sales mix changes. The 2%
decrease in underlying sales volume in the Custom Sheet & Rollstock segment was
primarily related to a decline in the packaging market impacted by the loss of a
government subsidized dry milk program where the customer utilized our rollstock
for the production of pudding cups. The increase in sales volume in the Color &
Specialty Compounds segment related to strength in the Building & Construction
and Transportation markets net of the loss of toll-compound business to a
customer in the electronics market that has been decreasing over the last
several years.

Operating earnings reported for the second quarter of 2006 were $28.0 million
compared to $6.3 million in the prior year second quarter. Included in operating
earnings for the quarter were $0.6 million of costs related to the expensing of
stock options resulting from the adoption of FAS 123(R) which became effective
in our first quarter of 2006 and $0.5 million related to special items from
plant restructurings. Operating earnings excluding stock option expenses and
special items were $29.2 million for the second quarter of 2006 compared to
$24.3 million in the prior year quarter, up 1.4 cents per pound sold to 7.6
cents in the second quarter of 2006. This increase reflects a material margin
that was 1.9 cents higher than last year's second quarter related to better
management of resin price changes partially offset by higher conversion costs
and lower selling and administrative costs. Conversion costs increased .8 cent
per pound sold related to an increase in freight and utilities expense of $3.4
million, partially offset by $1.7 million of labor-related cost reductions from
our 2005 restructuring activities.

Reported net earnings totaled $13.9 million or $.42 per diluted share for the
second quarter of 2006 compared to an $80 thousand net loss with no diluted
earnings per share in the second quarter of 2005. Net earnings excluding stock
option expenses and special items were $14.7 million or $0.44 per diluted share
for the second quarter of 2006 compared to $11.3 million or $0.35 per diluted
share for the second quarter of 2005. To clarify our discussions of performance
compared to the prior year periods we have included certain non-GAAP measures
that exclude both stock option expenses and special items. Refer to the GAAP to
non-GAAP reconciliations at the end of this Release.

Commenting on the results, George A. Abd, President and CEO, stated, "We were
pleased with our progress in realizing benefits from our reorganization over the
past 12 months. While freight and utility costs had a negative impact to our
results, the consistent improvement in our labor costs as well as the focus on
better margin levels through new product sales enabled us to come in a bit ahead
of schedule on our plan."

Mr. Abd also stated, "In the past year we have made tremendous progress in many
areas in our effort to improve the Company's operations, cost structure and to
refocus on return on investment. We are ahead of schedule for some of our plans,
particularly those related to cash generation and margin improvement, but we are
diligently focused on the many opportunities that remain. I am very pleased that
our team's performance in cash management has put us in the position to
restructure our debt while maintaining a high level of available borrowing
capacity to pursue both acquisition and internal growth opportunities."

SEGMENT RESULTS

CUSTOM SHEET & ROLLSTOCK--Net sales in our Custom Sheet & Rollstock segment were
$240.9 million in the second quarter of fiscal 2006, an increase of 1% from the
$238.1 million produced in the same three month period of 2005. This sales
increase reflects a 4% increase in price/mix less an underlying sales volume
drop of 2% and a 1% decrease from the sale of our Canadian corrugated sheet
business. The volume decrease came primarily from a drop in packaging sales,
impacted by the loss of a government subsidized dry milk program where a
customer utilized our rollstock for the production of pudding cups, net of some
increases in volume at both our Mexico facility for the appliance market and
Donchery facility for the multi-layer gas tank project.

This segment's operating earnings for the second quarter of fiscal 2006 were
$20.5 million compared to $9.8 million in the second quarter of the prior year.
The segment's operating earnings included $.1 million of a gain on sale of
assets from a facility closed in the 2005 restructuring and $.2 million for the
expensing of stock options in the second quarter of 2006 and $9.5 million of
restructuring and exit costs and fixed asset charge in the second quarter of
2005. Excluding stock option expenses and special items, operating earnings of
$20.6 million were up $1.4 million in the second quarter of fiscal 2006 from the
comparable 2005 quarter. This increase was driven by an increase in material
margin of 2.1 cents per pound sold less higher conversion costs of 1 cent per
pound sold. The material margin benefited from a neutral to downward resin price
market, the concerted effort to expand margins to address increased freight and
utilities costs and improved profitability from our sheet operation in Mexico.
The higher conversion costs reflect increases in freight and utilities costs,
offset by lower labor-related costs resulting from our 2005 restructuring
activities.

COLOR & SPECIALTY COMPOUNDS--Our Color & Specialty Compounds segment's net sales
increased to $122.3 million or 8% over last year's $113.4 million. This sales
change was comprised of a 7% increase from price/mix and 1% increase from
volume. The 1% volume increase reflects growth in Building & Construction and
Transportation markets, partially offset by the elimination of a tolling project
(material provided by the customer that is only converted by Spartech) for a
customer in the electronics market (1% negative impact). Disruptions associated
with our Donora consolidation efforts were less for the quarter as the project
moves forward.

The following table provides underlying sales trends for this segment's two
major product categories: Tolling & Resale and Proprietary Products (engineered
compounds and color concentrates).

SPARTECH CORPORATION
SECOND QUARTER 2006 EARNINGS
ADD 3


This segment's operating earnings in the second quarter of fiscal 2006 were $8.1
million compared to $2.8 million in the second quarter of fiscal 2005. The
segment's operating earnings included $.6 million of restructuring and exit
costs and $.1 million for the expensing of stock options in the second quarter
of 2006 and $4.4 million of restructuring and exit costs in the second quarter
of 2005. Excluding stock option expenses and special items, operating earnings
of $8.7 million were up $1.4 million in the second quarter of fiscal 2006 from
the comparable 2005 quarter. This increase was driven by an increase in material
margin of 2.2 cents per pound sold less higher conversion costs of 1.7 cent per
pound. The material margin benefited from our focused efforts to manage margins
for changes in resin and certain conversion costs.

ENGINEERED PRODUCTS - Net Sales in our Engineered Products segment in the second
quarter of 2006 were flat with last year's second quarter. Sales decreases for
the divestiture of assets related to our West Coast profiles operations in the
fourth quarter of 2005 were mostly offset by strong sales to the Lawn & Garden
market for our Wheels business.

This segment's operating earnings for the second quarter of fiscal 2006 were
$3.4 million compared to an operating loss of $1.7 million in the second quarter
of fiscal 2005. The segment's operating earnings included $3.5 million of
restructuring and exit costs in the second quarter of 2005. Excluding stock
option expenses and special items, operating earnings of $3.4 million were up
$1.6 million in the second quarter of fiscal 2006 from the comparable 2005
quarter. This $1.6 million increase was related to significant improvement in
the profitability of our Wheels operation which experienced start up costs and
disruptions in 2005 related to the move of an operation from California to
Mexico and the ramp up in production for a significant new customer. In
addition, the second quarter of 2005 included losses from its West Coast
profiles operation of $0.3 million.

CASH FLOW PERFORMANCE

Cash provided by operating activities was $26.1 million in the second quarter of
2006 and $40.9 million for the first six months of 2006 compared to $22.0
million in the second quarter of 2005 and $13.4 million for the first six months
of 2005. This improvement in operating cash flow primarily reflects stronger
earnings and working capital improvements, specifically an average decrease of
two days of sales outstanding and an inventory turn increase from 8.5 times to
10.7 times as of April 2006. This cash flow from operations has provided the
opportunity to pay down debt by $28.9 million in the first half of 2006 compared
to borrowing $24.6 million for the same period of 2005, after excluding debt
repayments from the $35.0 million reduction in cash in the first half of 2005.
As a result, our debt to equity ratio of .82 to 1 is the lowest level in the
last ten years.

SPECIAL ITEMS AND STOCK OPTION EXPENSES

The special items recognized in the second quarter of 2006 related primarily to
restructuring and exits costs for the consolidation of our Donora, Pennsylvania
and Arlington, Texas facilities and totaled $.5 million pre-tax ($.3 million
after tax). In addition, we recognized expenses of $.6 million pre-tax ($.5
million after tax) related to the expensing of stock options in the second
quarter of 2006. In the second quarter of 2005, we recognized $10.4 million in
fixed asset charges ($6.5 million after tax) and $7.6 million in restructuring &
exit costs ($4.8 million after tax).

Collectively these special items and stock option expenses totaled $1.1 million
in the second quarter of 2006 compared to $18.0 million in the second quarter of
2005. Excluding special items and stock option expenses, operating earnings were
$29.2 million in the second quarter of fiscal 2006, up $4.9 million from the
comparable 2005 quarter.

SUBSEQUENT CAPITAL RESTRUCTURING

In June 2006, we initiated a series of capital structure transactions to take
advantage of the current debt position resulting from our favorable operating
cash flows that paid down over $110 million of debt in the last four quarters.
These transactions consisted of the following:

     -    Amended our Bank Credit Facility to increase it from $200 million to
          $300 million and extended it for a new five year term;

     -    Closed on $50 million of a new Private Placement of 5.78% unsecured
          notes with a five year term;

     -    Redeemed $50 million of our 6.5% convertible preferred securities; and

     -    Notified the holders of the $100 million in 7.0% convertible preferred
          securities of their redemption later in our third quarter of 2006.

These transactions will result in a combined charge of $5.5 million (including
the non-cash write-off of unamortized debt issue costs of $1.8 million) in the
third quarter of 2006. These transactions will eliminate the potential dilutive
effect of a future conversion of the convertible debentures. Using our current
interest rates, we estimate an annual interest savings of $1.7 million ($1.1
million after tax) from these transactions. Overall, the result of these
transactions provides a more efficient capital structure to finance our future
growth.

EARNINGS GUIDANCE

As a result of significant progress to date in our business improvement and
balance sheet management efforts, the Company is increasing its earnings
guidance for fiscal 2006 by $0.05 per share to a range of $1.28 to $1.38
excluding the effect of FAS 123(R) and special items. This results in guidance
of $1.22 to $1.32 per share including the impact of stock option expensing of
approximately $0.06 per share for the full year, but before the impact of
special items related to restructuring and debt refinancing activities. A
summary of our guidance follows:

NON-GAAP MEASURES

We believe that operating earnings, net earnings, and earnings per share
excluding special items and stock option expenses, which are non-GAAP
measurements, are meaningful to investors because they provide a view of the
Company's comparable operating results. Special items (including fixed asset
charges and restructuring & exit costs) represent significant charges that we
believe are important to an understanding of the Company's overall operating
results in the periods presented. Stock option expenses are included as a
non-GAAP reconciling item since our analysts' and public estimates have not yet
considered the effect of these expenses and would not be comparable to our
reported results. Such non-GAAP measurements are not in accordance with
generally accepted accounting principles (GAAP) and should not be viewed as an
alternative to GAAP measures of performance. A reconciliation of GAAP
measurements to non-GAAP can be found at the end of this Release.

                            (IN THOUSANDS, UNAUDITED)

We believe that operating earnings, net earnings, and earnings per share
excluding special items and stock option expenses, which are non-GAAP
measurements, are meaningful to investors because they provide a view of the
Company's comparable operating results. Special items (fixed asset charges and
restructuring and exit costs) represent significant charges that we believe are
important to an understanding of the Company's overall operating results in the
periods presented. Stock option expenses are included as a non-GAAP reconciling
item since our analysts and public estimates have not yet considered the effect
of these expenses and would not be comparable to our reported results. Such
non-GAAP measurements are not recognized in accordance with generally accepted
accounting principles (GAAP) and should not be viewed as an alternative to GAAP
measures of performance. The following reconciles GAAP to non-GAAP measures for
operating earnings, net income, and earnings per share excluding special items
used within this release. Amounts are unaudited and in thousands, except per
share data.
